i found this half dollar in my roll searches recently. I first overlooked it when I was edge searching, but the machine kicked it out since it is Silver. My dump bank's machine is calibrated to reject silver halves, quarters etc. I moved this to ask those on this board what the opinion is. The coin has very clearly defined layers, silver and copper. Yet, I thought the 40% halfs were a silver copper alloy so the metals would have been amalgamated correct?, and there would not be a layer of silver and a layer of copper. Clearly it is 2-3 years from being a clad planchet error. It's not dirt because the copper band has a copper sheen to it. I have searched hundred of thousands of half dollars and have found thousands of 40/90 halfs but never have seen this. So experts on error coins, because I am not one, what's going on here? The defined copper layer is more defined than the pictures show. By the way it rings like silver.
It's a normal 40% half dollar. Some look like this, other's don't. It's a clad half similar to the current one's, except from 1965 - 1970 they contained silver in each layer to make the 40% silver content.
I have a half dollar that shows the copper looking band around the edge. It weighs same as the 68, and also rings like 40% silver 68. Both coins weigh at 11.3, any ideas
